To It IU7l U777/ it may concern.-

lie it known that I, Snvnorn t. PALMER, a citizen of the lnited States, residing at South Nor-walls in the county of Fail-held and State of Connecticut, have ii'iveuted certain new and useful Improvements in llat- Dipping Apparatus for llat -l:or1ning Machines; and I do hereby declare the following to be a full, clear and exact description of TO the invention, such as will. enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to certain improvements in hat-forming machines; but

especially appertains to an apparalui fordipping hat-bodies while on the cone.

The object of this invention is to accomplish the dipping oi". the hat-bodies automatically by mechanical means, while at the same time the speed at which the hat is dipped is variable; and with these ends in view my invention consists in thedetz'iils of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may understand how to make and use the same, I will proceed to describe its construction and oper- 3o ation in detail, rct'erriug by letter to the ac companying dra'vvings, forming a part of this specificathm in wh ich Figure 1 is a side elevation of my improvement; Fig. 2,21 'i'ront Ol0\'tttl( ll,tll0 plungerrod being broken away; and Figs. 3, l, and 5 are detail detached views showing the relative positions of the crank and reciprocating lever during the operation of subnicrging the hat-body.

40 Similar letters denote like parts in the several figures.

A is the tub containing water within which the hat-bodyA is to be dipped, and Bare guide-lugs lll'tljQC-bll'lg from said tub.

C is the platform on which the cone is placed, and l) is a bail secured at the ends to the platform and passed through the lugs 15, for the purpose of guidin and steadying the platform during the operation ot dipping.

E E are hangers and I? is a counter-shalt jourualed within said hangers.

(-r is a pulley loose on said shaft and having a hub ll, within which latter are formed notches a.

I is a disk rigid on said shaft, and J is'a bolt extending loosely through said disk and adapted to be thrown within the notches (I, as will be presently explained. A spring, I), scoured to said d is]; and bearing against the rear of said bolt, tends to shoot thelatterforward,

K an arm secured to the hanger E, and L is a detent pivoted to said arm and sustained in elevation by a coil-spring, c, attached at its extremities to said arm and detent. The nose of said detent is beveled, as soon at (7, and is within the lield of travel of the heel end of the bolt .l, so that when the said heel end is carried against the beveled nose the bolt will be withdrawn against the resiliency of the spring I), and the said heel will be arrested. by the stop-lug c at the base of the beveled nose.

M is a crank rigidly secured on the shaft F.

N is a lever pivoted at the rear end to a hanger, (J, and l is a rigid rod pivoted at its extremities to the forward end of the leverN and the top of the bail, respectively.

Q is a slot within the body of the lever N, and within this slot travels the pin R of the crank It, so that it will be clearly seen that motion is communicated to the rod 1 from the crank M through the intermediate lever, N. The contour and extension of the slot Q are such with respect to the line of travel of the crank-pin that a vertical reciprocation of variable speed will. be imparted to the lever ac-. cording to the angles which said slot assumes to said line of travel during the circuit of the crank-pin. Thus at Fig. 1 this angle will be seen to be very steep, and therefore the lever will be carried downward at a very fast rate when the crank is revolved in the direction indicated by the arrow until the position at 'lr ig. 6 is reached, when that part of the slot inthc immediate path of the pin is nearly parallel with the line of travel of thepin, and the movement of the lever will therefore be continued at a much slower speed until the position shown at Fig. lis reached, where the said slot coincides with the line of travel of said pin throughout an arc of about sixty degrees, the result of this being of course that other hat-body.

the lever has no movement during the traversing of said are.

The diagram at Fig. 5 shows the relative position of the crank, pin, and slot When the pin has reached the end of said are and immediately prior to the elevation of the lever by the return movement of said crank.

Hat-bodies are at present dipped by hand, the hat being transferred on the forming-cone directly to the dipping-tub, the combined op eration of forming and dipping requiring the service of an extra man on every formingmachine.

By the use of my improvement at single operator removes the cone with the hat thereon from the forming-machine, places said cone on the'platform C, pulls the cord S, attached to the detent L, thereby releasing the bolt J and effecting an engagement between the latter and the notched hub H, whereby the crank and lever are operated to lower said platform to submerge the hat, and returning to the forming-machine places another cone therein and superintends the initial formation of an- He then slips the first hat (which has in the meantime been dipped) from its cone, and the second hat having by this time been formed, he removes the same on its cone from the forming-machine; and after placing the last-mentioned hat on the dipping-platform he places the first cone back in the forming-machine, and after superintending the initial formation of a third hat slips the second hat, which has in the meantime been dipped, from its cone, and so forth. It will thus be seen thata single operator attends continuously to both the forming and dipping of the hat-bodies.

It is all important that the hat should be submerged at a speed which gradually decreases as the water continues to rise within the cone, for the reason that the air becomes so compressed within the cone that the speed of dipping must be so regulated as to allow the compressed air to escape gradually through the hat-body, otherwise the hat-tip will be blown out or so distorted as to render the hat worthless. \Vhen the hub II is clutched by the bolt J, on the release of the latter by pulling the cord S, the shaft F will only revolve once, since the bolt on the completion of its circuit will strike against the inclined nose of the detent L, and thereby be withdrawn from the notched hub and arrested in its movement by the stop 6, as hereinbefore set forth, thus bringing the crank to a normal position at rest, and causing the platform C to remain in elevated position, shown at Fig. 1.

In order that the action of the water and air within the cone during the process of submerging may be uniform in all instances, it is important that there should be a positive movement to the platform, and therefore a rigid connection is necessary between the lever N and said platform, and the rod P constitutes a salient part of my invention.

The operation of the crank-pin within the slotted lever of course renders the lever capable only of a limited variable motion, for the reason that during the fastest and slowest movements of the lever the said pin travels in opposite directions within the same section of the slot. While this construction is admirably adapted for forming comparatively fine grades of hats, still in order to form the finest grades, it is necessary that the opera tion of dipping should not be effected by a limited variable motion, and I have accordingly shown and described in my pending application, Serial No. 287,184, filed October at, 1888, a construction in which a face-cam is used instead of the cam-slotted lever, in order that there shall be no limit to the fastest and slowest movements in the operation of dipping the hats.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hat-dipping apparatus, the combination, with a crank, of a pivoted lever having a slot within which the pin of said crank extends, and the cone-supporting platform suspended from the forward end of said lever, substantially as set forth.

The combination, with a revolving crank and a pivoted lever having a slot within which the crank-pin travels during its circuit, of a rod pivotally hung from the'end of said lever, and the cone-supporting platform suspended from the rod, substantially as set forth.

3. In combination with the reciprocatory lever and the bail of the cone-supporting platform, the rigid rod connecting said bale and lever, whereby a positive and synchronous movement is imparted from the latter to the former, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
